HI  
When i use irb, sometimes i get a strage behavour especially when i do  
a error.  
As you can see from the below example, where it jumped from  
rb(main):034:0 to rb(main):035:1 when i did not close the block  
properly. now i lost my interactivity and dont know how to get back to  
the original session. I have to quit my window and restart irb again.  
is ther a better way of handling such situations
